Check out “Mexico”, not the James Taylor song of the same name, but a somewhat obscure Elvis track from Fun In Acapulco. Thanks to Tony D'Ambra of the invaluable films noir web site for reminding me of it, in a post about The Big Steal, a prime example of fiesta noir — a film that starts out noir but goes goofy when it gets south of the border.
Elvis's “Mexico” is a slight bit of material but Elvis makes it fun — and manages to remind me how much I miss Baja California and La Paz.
Elvis sings the song in the movie — it can also be found on the soundtrack album and on the two-disc set Command Performances which collects most of the songs from the Elvis movies not included on the various Masters box sets.
